Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an improvement in long-handled shears used particularly for pruning tall branches.

``Prior Art'' Although not specifically shown in the drawings, conventional long-handled scissors of this kind have a scissors portion on one end of the long shaft, a handle portion on the other end, and the handle portion and the scissors are connected inside the long shaft. The structure is such that the scissors are connected by a connecting shaft arranged on the handle, and the scissors can be opened and closed by operating the handle, while the long handle and the intermediate part of the connecting shaft are each divided, and each divided end is connected with the following hinge mechanism. are foldably connected via the

The hinge mechanism that connects the split ends of such a long handle generally includes a pair of connecting metal fittings that are rotatably joined via a shaft pin, and a pair of connecting metal fittings that are rotatably joined via the shaft pin. The first connecting fitting is fixed to one of the divided ends, the other connecting fittings are respectively fixed to the other divided end, and the other connecting fittings are attached to the locking fittings. By locking to one connecting metal fitting through the two, the split long handles can be fixed in a long unfolded state, and conversely, by rotating the locking metal fitting and releasing the lock from the other connecting metal fitting to one connecting metal fitting, The structure is such that the long split handles can be folded together.

Furthermore, the hinge mechanism that connects the divided ends of the connecting shaft consists of a pair of connecting pieces that are pivotally attached to both divided ends of the connecting shaft, and when the divided long handles are folded together, the divided ends of the connecting shaft are It has a structure that allows it to be bent into a letter shape.

Therefore, the conventional long-handled scissors having such a configuration are used in a long unfolded state, and the long handles can be folded when stored or transported.

``Problems to be solved by the invention'' However, since conventional long-handle scissors have a folding structure for the long handle, the long handle and the connecting shaft have a split connection part that is extremely difficult to solve. Since a complicated hinge mechanism is required, the number of parts increases considerably, which naturally increases the cost of the scissors themselves. There was a problem in that the mechanism often malfunctioned and the long handle itself could not be unfolded and folded smoothly.

Moreover, with conventional long-handled shears, once the split long handles are fixed in the unfolded state with the locking metal fittings mentioned above, it is absolutely impossible to freely change the overall length, so the height of the tall branches to be pruned In some cases, the length of the long stems also makes pruning difficult and inconvenient, which is a major problem in use.

In addition, although conventional long-handled scissors can be folded when stored or transported, the long handle itself is simply folded in half, so it is undeniable that the scissors as a whole are bulky. When doing this, it was often seen that the operator's fingers were accidentally caught between the split long handles.

"Means for Solving the Problems" The present invention was developed to effectively solve the problems of conventional long-handled scissors, and consists of providing a scissors part on one end of the long handle and a handle part on the other end. The long handle is divided into two approximately at the center, and one divided handle is connected to the other divided handle. The split handle is slidably housed in the split handle, and any part of the split handle is fixed to the end of the other split handle via a fixing member, and a guide groove is formed on the side surface of the other split handle. A connecting member is movably provided in the guide groove, and the connecting shaft is also divided into two parts, and the divided connecting shaft arranged in one divided handle is fixed to the connecting member, and the divided connecting shaft arranged in the other divided handle is fixed to the connecting member. A structure is adopted in which the split connecting shaft disposed in the connecting member is removably fixed to the connecting member.

"Operation" Accordingly, in the present invention, one split handle is pulled out from the other split handle, both split handles are fixed in an extended state via the fixing member, and at the same time, the split connecting shafts are connected to each other by the connecting member. Once connected via the handle, all you have to do is open and close the scissors by operating the handle.
Tall branches can be easily pruned.

Moreover, when pulling out one split handle from the other split handle, by selecting the amount of pull out, the overall length of the long handle itself can be changed to a length suitable for the tall branches to be pruned, making it extremely convenient to use. becomes.

In addition, in the case of storage and transportation, the fixing of the fixed member and the fixation of the split connecting shaft arranged in the other split handle to the connecting member are released, and one split handle is stored in the other split handle. This makes it possible to reduce the length of the long handle itself to about half, making the entire scissors extremely compact and extremely easy to handle.

"Embodiment" Hereinafter, the present invention will be described in detail based on an embodiment illustrating the present invention.The long handle scissors according to the embodiment also basically have a scissors part 22 on one end side of a square long handle 21, and a scissors part 22 on the other end side.
